Windows 7: Video Card artifacts, Memory error, BSOD = all in one

20 Oct 2012   #1

Windows 7
Video Card artifacts, Memory error, BSOD = all in one

I bought used parts.

Intel Core i5-760
Asus P7P55D
OCZ Gold 8GB (4x2gb) DDR3 PC3-10666 CL9
Saphire Radeon HD 6850
Enermax Liberty 400Watt PSU ELT400AWT
For now I use HDMI cable not DVI to connect to a monitor.

When I first turned on computer first thing I saw were artifacts.

I thought video card is broken, so I need to change it, but that's not only problem I had.
I couldn't even install Windows 7 32 or 64bit. I got memory errors all the time.
So I removed RAMs one by one.
What I noticed with RAMs are -
1) with 4 RAM modules I couldn't install windows I got memory errors
2) With one RAM module computer didn't even start, just black screen and no beep sound at begin.
3) also computer didn't started when I put two modules in slot 1 and 3.
4) I could start computer and managed to install windows with two modules in slots 2 and 4.
5) I could start windows (already installed) with all 4 modules. And it showed 8Gb RAM. But time by time I got Memory

6) Windows Memory diagnostic tool didn't show any error.

I installed ATI drivers and artifacts became even worse.

Catalyst stops to work constantly, with all four RAMs windows explorer stops working and restarts all the time.

Sometimes I get blue screen.
